I am sorry for you @MikeyD and I can understand not wanting to wait that long. Unfortunately I don’t have any suggestions on what you could do about that.
@T_dub same about your thumb.
Reading those comments actually made me calm down regarding my practice a little bit. I really had a hardcore schedule and yesterday when reading the comments I “tested” my left hand and it was hard to stretch the fingers straight. A little bit like the muscle ache I get in my fingers from climbing so I took a break again yesterday. My hand is much better now.
So since I want to learn a lot and fast but don’t want to put a roadblock in my own way: Apart from the stretching exercises in hand care - are there any tips to prevent those issues from arising in the first place?
